A hardware enthusiast has built a compact 8-liter computer system inside an In Win CJ712 case that integrates dual graphics cards to run Lossless Scaling software in parallel, according to a report by Maxim Boldson published on GameGPU. The build combines gaming, CAD work, network storage, and a media center featuring an LG BU40N optical drive, with a total system cost reaching 4,135 euros including peripherals and a monitor.
Dual-GPU Architecture for Frame Generation
The core technical concept behind the build relies on splitting the workload between two low-power graphic accelerators to reduce strain on the main rendering pipeline, as detailed by GameGPU. The primary graphics operations are handled by a professional PNY RTX 4000 SFF Ada card equipped with 20GB of memory and a 75W power limit. A secondary XFX Radeon RX 6400 card, consuming 53W of power, runs the Lossless Scaling utility. According to the reported specifications, separating basic frame rendering from scaling and interpolation algorithms allows the utility to execute on the auxiliary chip without impacting response times or adding computational load to the primary GPU.
Real-World Benchmark Performance
Practical testing confirmed high efficiency when displaying high-resolution images on a 2560×1440 Dell UltraSharp U2724D monitor with a 120Hz refresh rate, according to the GameGPU report. In Crimson Desert, applying ray tracing and DLSS upscale profiles alongside a 2x hardware frame multiplier and 2x LSFG add-on yielded a stable 120 frames per second at high graphical settings. Furthermore, testing in Hogwarts Legacy at maximum settings with DLSS Quality mode enabled, motion blur disabled, and the LSFG 2x algorithm running without built-in generation pushed the frame rate to 143 frames per second.
Hardware Component Breakdown
According to the project specifications published by GameGPU, the system packs heavy computing power into a tight enclosure using the following components:
- Processor: AMD Ryzen 9 7900 (65W, 12 cores)
- Motherboard: MSI PRO B850M-A WiFi
- Cooling: Thermalright AXP90-X36 with Noctua NF-A9x14 PWM fan and an ARCTIC P8 slim case fan
- Memory: 64GB Corsair Vengeance DDR5-6000 CL30 RAM
- Storage: 4TB Lexar NM790 SSD
- Power Supply: Overtek Enhance ENP-7660L 600W
Did you know? The entire build fits inside an In Win CJ712 enclosure boasting an approximate volume of just 8 liters while housing a 12-core processor and dual GPUs.
Frequently Asked Questions
What is the primary function of the secondary GPU in this build?
According to GameGPU, the secondary Radeon RX 6400 runs the Lossless Scaling software in parallel to offload scaling and interpolation algorithms from the primary rendering card.
What are the total costs associated with this custom small-form-factor PC?
The total cost for the entire system, including peripherals and the monitor, reached 4,135 euros, as reported by Maxim Boldson.
How does the system handle high-end games like Hogwarts Legacy?
With maximum graphical settings, DLSS Quality mode, disabled motion blur, and the LSFG 2x algorithm, the system achieved 143 frames per second, according to the tested metrics.
